Collaborative Study to Evaluate a Paperboard Substitute for a Diffusion Capacity Standard

PTM Technical Report

August 2015

This collaborative study was undertaken to check if certain paperboard samples can be used to monitor diffusion capacity measurement instrument performance over extended periods of time. The results showed that the paperboard samples were stable at least over the period covered by the study. The paperboard samples may also qualify as a diffusion capacity transfer standard, alternative to the current unique commercial product, but further studies are required before this can be reliably concluded.
